Abstract: 1,021,370. Percussive drills. N. T. NELDAS. Nov. 19, 1962, No. 43648/62. Heading B4C. A rock drilling device comprises a drill holder 3 connected to a slide 2 which is reciprocable within a housing 11 by means of a rod 1, the movements of the rod and the movements of the slide being dampened by means of fluid pressure chambers 8, 9, 5 and 13 respectively. The rod 1 is provided with a piston-member 4 slidable in the chamber 5 which is formed in the slide 2, the piston dividing the chamber 5 into two pressure chambers 8, 9. The slide is formed with a piston-like portion 6 slidable in the chamber 13 and divides this chamber into two pressure chambers 14, 15. In operation, the rod 1 is reciprocated by some suitable mechanical means, such as a link-and-eccentric drive, movement upward of the piston 4 causing a port 10 to be uncovered, compressed air then being fed alternately into the chambers 8, 9 via a port 23, annular space 24, ports 18, 19. The movement transmitted to the slide causes the piston-like portion 6 to alternately uncover ports 18, 19 and so admit compressed air into the chambers 14, 15, thereby providing a cushioning effect for the tool holder 3. In the event of the compressed air being shut off, the slide, together with the tool holder, is raised by means of a spring-loaded piston 27 abutting a flange 30 on the slide 2, the piston being normally held down as shown while the compressed air is fed into the cylinder 26. Passages are provided in the slide 2, rod 1, and housing 11 for the introduction of lubricating oil to the mating surfaces of these parts.

Abstract: 954,878. Parametric amplifiers. MULLARD Ltd. Nov. 26, 1962, No. 44630/62. Heading H3B. A parametric amplifier or up-converter comprises a waveguide in which are mounted a voltage dependent capacitive diode D and an adjustable capacitive probe J extending towards the free end of the diode to form a lumped constant circuit tuned to be resonant at the signal frequency. An inductor H may be connected in parallel with the diode. Coaxial lines E, F with central conductors forming probes M, N extending towards the diode serve as input and output channels for the signal. A single coaxial line E or F may be used with a circulator for both input and output signals. A signal fed to the diode through one coaxial line may be extracted through the second coaxial line at the idler frequency to provide up-conversion. The waveguide is terminated by a short-circuiting piston which is adjusted to tune to the idler frequency the portion of the guide extending from the piston to side members G adjacent the diode. The side members G have a high cut-off frequency and offer a high impedance to the idle frequency while accepting the pumping frequency from the other end of the guide. The whole of the guide is tuned to the pumping frequency by a probe K. The necessary biasing arrangements for the diode are not shown.

Abstract: 1308120 Measuring pitch and roll HUGHES AIRCRAFT CO 4 Oct 1971 [5 Oct 1970] 46061/71 Heading G1N [Also in Divisions G4, H3] An electronic system responsive to sine and cosine information signals at a predetermined frequency comprises a phase-locked loop oscillator circuit which produces quadrature signals locked to the information signals. In the arrangement of Fig. 2, a carrier signal E sin wt applied to the rotor of a synchro transmitter 11 produces a 3- phase output which is fed to a 3-wire/2-wire converter 35 to provide sine and cosine signals related to the angular position # of the rotor shaft of synchro transmitter 11. These two signals are then applied to respective demodulators 37, 39 together with quadrature reference signals of angular frequency # and the resulting outputs, are summed in adder 73 to produce, via integrator 85, a control signal for oscillator 87 which is depen- (lent on the angle #. The oscillator operates at an angular frequency 4# and its output is divided down to provide the required two quadrature reference signals at angular frequency # by bi-stables 89, 91, 93. The loop will then lock with the phase angle α of the reference signal equal to #, and the reference signals thus repeats the angular position 6 of a remote rotor shaft. In use, Fig. 7 not shown) two such systems (107, 105) are employed to provide signals representative of the pitch, #, and roll, #, of an aircraft, which are then transformed from aircraft co-ordinates to earth co-ordinates in a resolution system (see Division G4) which employs further demodulators (DM) and a modulator (MOD).
